Innovation focuses on improving existing products or processes rather than inventing entirely new things. Joseph Schumpeter identified five patterns of innovation: introducing new goods or services, developing new production methods, opening new markets, finding new sources of supply, and reorganizing an industry. While inventions can drive innovation, a country or company does not need to invent something completely new to succeed - focusing on innovating existing technologies through combinations or improvements can also power economic growth, as Japan demonstrated by innovating on cars and TVs without originally inventing them.
